I thought there might be interest in two recent videos on Food.Farmer.Earth that pertain to aquaponics:
Small Scale Aquaponics
It's obvious Ann Forsthoefel of "Aqua Annie" is excited by aquaponics, the growing of plants fed by nutrients from fish, which in turn provide a source of food when they reach maturity. Watch the full video on YouTube:
Designing a Sustainable Aquaponics System: An Inventor's Touch
Curt Yungwirth's wants to increase the efficiences of a sustainable aquaponics system even further. Yungwirth, an inventor that holds several patents, hates solid state circuitry because he can’t repair them. But let him work with relay switches and standard circuits, he’s able to build almost anything, that he can see first in his mind. That’s how he built his integrated heat exchanger that dramatically improves both energy and water usage efficiencies in aquaponics.
